*Variables in this data set*: FAO soil suitability (two types), percent
of Matthews'* cultivated land in each K�ppen-Geiger** climate zone,
percent of Matthews' cultivated land -- using a revised classification
scheme -- in each K�ppen-Geiger climate zone, percent land area in each
K�ppen-Geiger climate zone weighted by Matthews' cultivated land,
percent land area in each K�ppen-Geiger climate zone weighted by a
revised Matthews' cultivated land classification, by country.

_Description of data (Word file)_ is a Microsoft Word document
(*agric-dta.doc*) containing a list of each variable within the
agriculture data set, a description of each variable, how the variable
was created, the source of the variable and any extra notes.

__

_Stata do file is a program (agric.do)_ written in Stata to load the
data in *agric.csv* and create the variable labels etc. in *agric.dta*.
It can be used as a model to load the data into other statistical
packages besides Stata.

__

_Stata data file_ is the Stata data set with the infectious disease data
by country (*agric.dta*).

__

_ASCII file_ is a comma separated value file (*agric.csv*) of the
agriculture data that can be opened as a spreadsheet in Excel, or used
in conjunction with the Stata do file (*agric.do*).

These data sets were created as part of The Center for International
Development?s ongoing research into the role of geography in economic
development (see www.cid.harvard.edu/economic.htm
<http://www.cid.harvard.edu/cidglobal/economic.htm>). They have been
created between 1998 and 1999. Please reference CID if you use this data
in a publication.
